View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.GSN is an oil-hardening, DESEGATIZED* high-carbon high-chromium die steel developed for high wear and abrasion resistance. It is outstanding among non-deforming oil-hardening steels, holding size almost as well as high-carbon high-chromium air-hardening die steels. It is used on specialized applications such as draw dies, forming rolls, powder-metal tooling and lamination dies.
